LATHING.

SPECIFICATION forming part of Letters Patent N o. 651 ,590, dated June12, 1906. application filed December 21,1899. Serial No. 741,172. (Nomodel.)

T0 at whom it may concern:

Be it known that I, FRANK E. BRIGHTMAN, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Lathing; and I do herebydeclare the following to he a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which :0 it appertains to make and use the same.

My invention relates to improvements in lathing or skeletons used in theconstruction of fireproof walls, ceilings,partitions,&c., moreespecially, however, to the class of me- :5 tallic lathing or skeletonswhich when suitably secured in position forms the foundation for thefilling which constitutes the body of such structures. In this class oflathing or skeletons it is of the first importance to combine withlightness strength and durability and to effect manufacture withfacility and cheapness. Various forms of construction of lathing of thistype have been produced, among them one having a twisted web withinclined convergent walled keys and the keys themselves arrangedparallel throughout the lathing.

My present invention or improvement embodies a structure or lathinghaving alternating keys or cups throughout its area with the walls ofall the rows or series longitudinally tapered and laterally inclined,but of alternating rows or series oppositely inclined, and the points ofconnection or union between them forming troughs or depressions in themedian plane of one row or series of keys and ridges or apices in themedian plane of the succeeding series or row of keys, the samealternating throughout the lathing, said depressions and ridgesindividually alternating diagonally, substantially as hereinafter morefully disclosed, andspecifically pointed out in the claims.

In the accompanying drawings,'illustrating the preferred embodiment ofmy invention, Figure 1 is a plan view. Fig. 2 is a section on line as wof Fig. 1. Fig. 3 is a section on the line y y of the same figure. Figs.4 and 5 are detail sections taken on the lines w w and z s,respectively, of Fig. 1.

In carrying out my invention I construct the lathing 1 preferably fromasingle piece of metal-light sheet metal. The peculiar construction ofthe lathe results in forming.

cup in its general outline is widest at its middle, as relates to itslateral area, and tapers toward each end. Taking the row or series ofkeys or cups 2 it willbe seen that they join or unite at theirlower orouter surface edges, as at 3, thus producing or forming what may betermed depressions or troughs in the median plane of the whole series orrow, permitting the spreading or inclining outward or upward of thewalls thereof throughout. In the row or series of cups or keys 2,alternating with the aforesaid row or'series of cups or keys, as aboveintimated, just the reverse is true, they being joined or united attheir upper or inner surface edges, as at 4, said points of unionalternating with the points of connection between the rows of cups orkeys 2, thus forming ridges or apices, as it were, in the median line orplane of the series or row of keys or cups. The individual apices anddepressions of the series or rows of keys or cups it will be seenalternate diagonally throughout the lathing. The walls of these cups orkeys 2, united at their upper or inner surface edges, are thus caused toincline inward or downward, the walls of the adjoining series of cups orkeys thus being oppositely inclined and serving to interlock thefilling-in portions of the plaster or mortar covering the lathing orskeletons.

Viewing the lath from the standpoint of Figs. 2 and 3 it will be seenthat each of the two contiguous Walls 4 of each series of keys .or cupsextending from side to side, as indicated by the double-headed arrow, isundulatory or wave-like in parallel lines with the longitudinal sectionof said cups or keys in its general outline, with the points ofconnection 5 between said walls arranged in approximately the same planeor horizontal alinement, thus presenting the same general surface areafrom above and below; also, that the points of connection of theadjoining walls of one such series of cups or keys are at the inner orupper surface edges of said walls and that the points of connectionbetween the walls of adjoining or successive series of cups or keys areat the lower or outer surface edges of said walls and the points ofconnection between. the walls of -the third series of cups or keys aresimilarly arranged as the first series of cups or keys, and so onthroughout the lath; also, that by reason of this construction theseries or rows of cups or keys are formed of the minimum amount ofmetal, only three instead of four walls,as would otherwise be required,being provided to constitute each two series of such cups or keys, andthat said walls themselves are each of a uniform cross-sectional areathroughoutand oftheminimumlightness or thinness consistent withstrength,while the stretch imparted to said walls in forming the keys orcups does not affect or reduce the general surface area of the lath.This is due to the fact that each wall, as above intimated, is reverselyinclined or deflected in the formation of each key or cup of all theseries or rows-of keys.

It will be seen that the lathing or skeleton is thus permitted to bemade of very light thin metal and yet possesses the requisite strengthor body by reason of the angularity of the respective walls of each keyor cup, this also being due to the alternate connection of the top andbottom edges of the walls ofthe cups or keys. It will also be observedthat by means of the aforesaid construction of lathing or skeleton thesame can be used with either side or face presented outward or reverselyput into position, which thus expedites and facilitates the operation ofapplying the lathing or skeletons and avoids mistakes. It will also beseen that 9116 wall of each series or row of cups or keys forms the adjoining wall of each succeeding series or row of cups or keys, thusproviding for the maximum utilization of metal and the greater number ofkeys or cups, increasing the efliciency of the plaster or mortar holdingcapacity of the lathing or skeleton.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Paten i 1, As a new article of manufacture, a lathingor skeleton having series or rows of keys or cups, the walls betweenwhich having theirpoints of connection arranged at alt-ernately-oppositeupper and lower surface edges of said walls, substantially as set forth.

2. As a new article of manufacture, a lathing or skeleton having seriesor rows of keys or cups, the walls between which having their points ofconnection in approximately the same plane and said points arranged atalternately-opposite upper and lower surface edges of said walls,substantially as set forth.

3. As a new article of manufacture, a lathing or skeleton having seriesor rows of keys or cups, the walls between which having their points ofconnection arranged at alternately opposite upper and lower surfaceedges of said walls, said walls being oppositely flared or inclined fromalternating points of connection, substantially as described.

4:. As a new article of manufacture, a lath ing or skeleton havingseries or rows of keys or cups, the walls between which having theirpoints of connection approximately in the same plane and said pointsarranged at alternately-opposite upper and lower surface edges of saidwalls, and oppositely flared or inclined from alternating points ofconnection, substantially as described.

5. As a new article of manufacture, alathing or skeleton having seriesor rows of keys or cups, the walls of which are undula tory or wave-likeand in parallel lines with the longitudinal section of said cups or keysand their points of connection arranged at alternately-opposite surfaceedges, substantially as set forth.

6. As a new article of man ufaeture, a lathing or skeleton having seriesor rows of cups or keys, the walls of which are undulatory or waverlikeand have their points of connection arranged in approximately the sameplane and at alternately-opposite surface edges, substantially as setforth.

7. As a new article of manufacture, a lathing or skeleton having seriesor rows of cups or keys, the walls of which are undulatory or wave-likein parallel lines with the longitudinal section of said cups or keys andhave their points of connection arranged in approximately the same planeand at alternately-opposite surface edges, said walls also beingoppositely flared or inclined from alternating points of connection,substantially as set forth.

8. As a new article of manufacture, a lathing or skeleton having seriesor rows ,of keys or cups, with the points of connection between thewalls of said keys or cups arranged in approximately the same plaue andat alternately-opposite upper and lower surface edges of said walls, thewalls being oppositely flared or inclined at alternating points ofconnection, all being formed in a single piece, substantially as setforth.

In testimony whereof I afllx my signature in presence of two witnesses.

FRANK E. BRIGHTMAN.
